RUSSIA – new SORG furnace producing mineral fibre for insulating wool
Mineral fibre is a common alternative to glass fibre for insulation purposes. They are normally produced by melting basalt, a volcanic mineral of variable composition. Some melt relatively easily, but others, such as porphyritic types are extremely difficult to melt.

A new SORG furnace at Belgorod, south of Moscow, is currently melting 120 tons per day of this difficult material for the production of mineral insulating fibre. The furnace is gas heated, and utilises a steel recuperator for waste heat recovery. An electric booster is also installed in the furnace. The short forehearth channel to the outlet is heated by gas and electricity.
